The ability to perform a direct search for meteoroid streams present within photographic and radar data sets is important in order to provide analyses of the structure of these streams, to enable their removal from the data set for sporadic background studies, and to assist in studies of their progenitor bodies. In the past searches have used dissimilarity functions, called D ‐criteria, to find orbits within a given dissimilarity of a particular mean stream orbit. Here we extend this method to enable the statistical significance of the stream members found to be established – this significance is determined by testing against similar areas of orbital element space. The data set provided by the AMOR meteoroid orbit radar is systematically studied using this method with reference to a large listing of mean stream orbits found in other studies.
